Sierra Clark is a PhD student in the department of Epidemiology and Biostatistics at Imperial College and a member of the Global Environmental Health Research Group and the Pathways to Equitable Healthy Cities project. Sierra is a Canadian Institutes for Health Research PhD and an Imperial College Presidents PhD scholarship award holder.  

Sierra’s research focuses on measuring and modelling noise pollution, different types of urban sounds, and their health burden, in the city of Accra, Ghana. 

Prior to joining Imperial, Sierra completed a MSc in Epidemiology and a Bachelor of Arts (Hon) in Geography at McGill University in Montreal, Canada.

During her MSc, Sierra was a National Geographic Young Explorer which partly funded her research in rural China on household air pollution, cardiovascular health, and the effectiveness of improved cookstoves to reduce exposures and improve health. 

While an undergraduate student, Sierra was a member of the Indigenous Health Adaptation to Climate Change (IHACC) group where she conducted research on the factors impacting retention of mosquito nets among Indigenous Batwa in Uganda and qualitative research on the lived experience of acute gastrointestinal illness among the same population.
